Sturmey Archer blog is reporting the long-awaited 3-speed fixed cog system is finally to prototype. Made famous by Sheldon Brown is the SA ASC 3-speed fixed. The cogs are fixed - sure, but by the magic of internal gearing, there various speeds are fixed.

I can certainly see the value here. I live on a big hill. Rolling down in the morning with my 68 inch gear can be an excercise in leg speed. On the way home - it’s standing all the way. What if I could run 68 on the flats, 85 on the downhills, and 50 on the uphills? How novel, and coming to a hipster near you I’m sure.
